The piecewise function is
(a)
\All possible values of for which the function is mathematically correct is the domain of a function.
The domain of is all real numbers.
(b)
\Find the intercepts
\Find the -intercept by substituting
.
If , the function is
.
Substitute in above function.
The value of which is not to be considered because
.
There is no -intercept.
Find the -intercept by substituting
.
The function is not defined at
.
The function is defined at
.
The intercept is .

Graph:
\1). Draw a coordinate plane.
\2). Plot the points found in the table and connect the plotted points
\3). Label the intercept points.
\
(d)
\All possible values of is range of a function.
Observe the graph:
\The range of function is .
The range in interval notation .
(e)
\The function is discontinuous at because the function has hole as
.
